Mu waves, also known as mu rhythms, comb or wicket rhythms, arciform rhythms, or sensorimotor rhythms, are synchronized patterns of electrical activity involving large numbers of neurons, probably of the pyramidal type, in the part of the brain that controls voluntary movement. person suppresses mu wave patterns when he or she performs a motor action or, with practice, when he or she visualizes performing a motor action. This suppression is called desynchronization of the wave because EEG wave forms are caused by large numbers of neurons firing in synchrony.
The Mu wave is a brain frequency which has been observed and studied since the 1930âs. Mu waves are in the range of 8-13 Hz and arise from large groups of neurons in the brain.Recently Mu brain waves have been associated with the âmirror neuronâ system that activates when we watch another personâs activity.lpha Waves: 8-13 Hz. Alpha is the brain wave associated with relaxed, daydreaming states of mind; itâs a state of relaxed, detached awareness. Many people are âin alphaâ while watching TV. Alpha is often called a âhypnogogicâ state because you may experience spontaneous mental imagery.
